This patch release fixes an issue with recent SciPy releases (1.16+) that prevented statsmodels from importing. It also addresses some small changes that improve future compatibility.

This page provides a series of examples, tutorials and recipes to help you get started with statsmodels. Each of the examples shown here is made available as an IPython Notebook and as a plain python script on the statsmodels github repository. We also encourage users to submit their own examples, tutorials or cool statsmodels trick to the Examples wiki page SARIMAX: Frequently Asked Questions (FAQ) State space modeling: Local Linear Trends Fixed / constrained parameters in state space models

API stability is not guaranteed for new features, although even in this case changes will be made in a backwards compatible way if possible. The stability of a new feature depends on how much time it was already in statsmodels main and how much usage it has already seen. If there are specific known problems or limitations, then they are mentioned in the docstrings. TreatmentEffect estimates treatment effect for a binary treatment and potential outcome for a continuous outcome variable using 5 different methods, ipw, ra, aipw, aipw-wls, ipw-ra. Standard errors and inference are based on the joint GMM representation of selection or treatment model, outcome model and effect functions. statsmodels.discrete.truncated_model.HurdleCountModel implements hurdle models for count data with either Poisson or NegativeBinomialP as submodels.

Three left truncated models used for zero truncation are available, statsmodels.discrete.truncated_model.TruncatedLFPoisson, statsmodels.discrete.truncated_model.TruncatedLFNegativeBinomialP and statsmodels.discrete.truncated_model.TruncatedLFGeneralizedPoisson. Models for right censoring at one are implemented but only as support for the hurdle models. This very simple case-study is designed to get you up-and-running quickly with statsmodels. Starting from raw data, we will show the steps needed to estimate a statistical model and to draw a diagnostic plot. We will only use functions provided by statsmodels or its pandas and patsy dependencies. After installing statsmodels and its dependencies, we load a few modules and functions:

pandas builds on numpy arrays to provide rich data structures and data analysis tools. The pandas.DataFrame function provides labelled arrays of (potentially heterogenous) data, similar to the R “data.frame”. The pandas.read_csv function can be used to convert a comma-separated values file to a DataFrame object. patsy is a Python library for describing statistical models and building Design Matrices using R-like formulas. This example uses the API interface. See Import Paths and Structure for information on the difference between importing the API interfaces (statsmodels.api and statsmodels.tsa.api) and directly importing from the module that defines the model.

The statsmodels code base is hosted on Github. To contribute you will need to sign up for a free Github account. We use the Git version control system for development. Git allows many people to work together on the same project. In a nutshell, it allows you to make changes to the code independent of others who may also be working on the code and allows you to easily contribute your changes to the codebase. It also keeps a complete history of all changes to the code, so you can easily undo changes or see when a change was made, by whom, and why.

To install and configure Git, and to setup SSH keys, see setting up git. To learn more about Git, you may want to visit: Below, we describe the bare minimum git commands you need to contribute to statsmodels. statsmodels is a Python module that provides classes and functions for the estimation of many different statistical models, as well as for conducting statistical tests, and statistical data exploration. An extensive list of result statistics are available for each estimator. The results are tested against existing statistical packages to ensure that they are correct.

The package is released under the open source Modified BSD (3-clause) license. The online documentation is hosted at statsmodels.org. statsmodels supports specifying models using R-style formulas and pandas DataFrames. Here is a simple example using ordinary least squares: You can also use numpy arrays instead of formulas: Have a look at dir(results) to see available results.

Attributes are described in results.__doc__ and results methods have their own docstrings. Please use following citation to cite statsmodels in scientific publications:
